Using Vision Modeling to Define Occupational Vision Standards  (2003)
Abstract Header
A methodology is introduced to assist in the construction of performance-based occupational vision standards. A simple image discrimination model is first calibrated using stimuli representative of airframe and powerplant cracks. It is then used to predict simulated crack visibility for cracks of different lengths and widths. Visual acuity declines are simulated using a Gaussian blur function on the crack images. This modeling technique can generate the data necessary to construct empirically based occupational vision standards.
